Y Y 'Y n 1 claim.` l(o1. 1oz-24) Y 'Y This invention relates to a flareor rocket-for use with aeroplanes. and the like, and has for its primaryobject to provide a simple and eilicient means for automaticallyigniting the illumina t after the rocket lis dropped from an aeropla e.A further object of. this invention is to provide a rocket or flare inwhich a parachute connected to the illuminant is simultaneously releasedwith the igniting of the expellant charge.

With these and other objects in view, the invention consists in thecombination of a barrel, with a detachable tail cover provided withwings, a parachute inserted into the rear end of the barrel is connectedby a cable to a container for an illuminant, a tinder and an expellantcharge arranged within the barrel. One end of aQwick is embedded in theexpellant charge and the opposite end is connected to an igniting zumeans, which latter, is actuated by a threaded propeller shaftwhenscrewed to the innermost position in an internally threaded socket xedto a cover on the front end of the barrel, said propeller shaft being4rotated vby means of a propeller keyed thereto when dropped from anaeroplane or the like.

'I'he igniting means may be either electrical` or pyrophoricg and asafety locking means is provided for preventing rotation of thepropeller shaft when the rocket is stored.

recting wings, fitted into the rear end of the' 40 barrel; 2 is theparachute; 3 is the barrel; 4 and 5 are the dividing discs andcrosspieces between which there is a space for containing the cords:

connected to the edges-of the parachute 2; 6 is a wooden cover abovewhich lies the suspen- ,45 sion cord connected to the parachute; 8 is a,

disc varranged in a recess in a disc 9 of nonigniting material, I0 isthe active mass of the illuminating device provided below with a bed ofspecial tinder 25, under which there is a bed of 50 black gunpowder I2.

The parts designated by the numerals 1, 9, I0, 25 and I2 are containedin an envelope I I, placed in the barrel 3. Below the mass of blackgunpowder I2, is a disc 5a and a wick I3, one end of which is embeddedin the gunpowder I2, and 5 the opposite end 23 passing through a cover6a is formed into a combustible match 24 in contact with an electricalspark produced between the terminals I4, when an electrical circuit isclosed as hereinafter set forth. 10

One of the terminals is mounted upon an insulating disc I5 secured to acover 2l by means of a ring 5b. Said cover 2| is fixed to front end ofthe barrel 43 as shown in Fig. 2.

`An internally threaded socket I B interposed 15 between the cover 2land disc I5 receives a threaded propeller shaft I'I containing anelectric battery I8 and a propeller 20 is secured to said shaft Il bymeans of a` conical nut I9.

'A safety locking means is provided for preventing rotation of thepropeller shaft I'I when not in use, which consists of a pin 21 providedwith a4 ring shaped handle 28, saidpin passes through an aperture 2liformed between the socket I6 and shaft I1 25 I claim:

An aerial flare comprising a barrel. a detachable tail cover providedwith vanes fitted on the rear end of said barrel, a parachute within therear end of the barrel, a container for an illu- 30 upon the base platecontacting with the free end of said wick and adapted to be electricallyconnected to said battery on said hollow propel- 45 ler shaft moving tothe innermost4 position in said socket by rotation of the propellershaft during the fall of the flare. n
